Product Description
Choose PTFE septa when chemical resistance matters most. These replacement septa fit 10-425 caps and present an inert surface to aggressive solvents, making them a dependable choice for single-injection work or samples that attack silicone. They also let labs rebuild caps on demand.
This listing is for MicroLiter catalog number 10-0010: PTFE Septa for 10-425 Caps, Pack of 100. Each septum is made of PTFE and sized for 10-425 open top screw caps. PTFE septa do not reseal after piercing the way silicone-backed septa do, so they are best suited to methods with one injection per vial or where re-injection is not planned. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
